To estimate the price of the 2015 Mercedes C300 I4 2.0L Turbocharged Top sedan with 107000 miles, I considered the following data points: 1) A 2017 Mercedes C300 I4 2.0L coupe with 91000 miles sold for SAR 113500 on 2023-05-04. Adjusting for the older model year and higher mileage, I estimate a depreciation of around 15% per year and additional depreciation for mileage. 2) A 2016 Mercedes C300 I4 2.0L Turbocharged Top sedan with 102000 miles is listed for SAR 88500. 3) A 2017 Mercedes C300 I4 2.0L Twin Turbo AMG Top sedan with 124000 miles is listed for SAR 70500. Considering the car's condition, mileage, and the fact that it is a year older than the 2016 model, I adjusted the price downwards from the listed prices.
